I'm calling on those who help diagnose the problem. This fall I was charging the batteries every weekend since they were discharging all the time to the point I could not start the vehicle. Up to the point I got tired and changed the batteries with 2 new ones (GR65, 900CCA 165 reserve) about two weeks before Xmas. Did a 3800 mile drive from Montreal to Lafayette, LA for Xmax, no problems until today. Truck would not crank and I'm charging the batteries as I'm typing. The truck is not used daily, stayed parked for the past 2 days, probably enough to discharge the batteries.
I will try the IOD test tomorrow per the service manual. Cannot see how there could be a problem with the grounds, its an 04, pratically new, and so are the batteries !
The only thing I might think it could be (... and this is were you can put your 2 cents or more...), is that I pulled the horn fuse (#45) late this summer since the horn was becoming erratic, almost possessed when it was parked. Sometimes long, but mainly shorts bursts of honking. Drove me and the neighbors nuts until I pulled the fuse. I have to get this checked by the dealer, just been putting it off ($$$
). Probably the horn pad, but I don't want to be fiddling in the air bag. My thought is that maybe the circuit is still drawing current draining the battery (locking the truck, accidently pushing the panic button, or something else...I have no idea).
I wasn't expecting this with new batteries, I tells me that I did not solve the problem. Anyone have any ideas and recommendations !
Thanks !
